5 Claims. l Y

The present invention relates to a carpet fastening device whereby the carpet may be held in fixed position with respect to the floor.

Heretofore such fastening means have been provided which have required molding or the like strips for installation and are diflicult to install or which have been so formed that they are inefcient and difficult to connect the rug thereto and to remove the same, therefrom.

An object of the present invention has provided a device which is inexpensive to manufacture, may be readily installed, and which will securely hold the margin of the carpet and yet enable the carpet to be readily removed therefrom for adjustments should the same be desired.

This is accomplished according to the present invention by providing a strip, preferably of metal, with a bend extending longitudinally thereof to provide an` upper and a lower section. The lower section is provided with means whereby it may be secured to the floor and the upper section is provided with a smooth, uninterrupted edge about which the margin of the carpet may be folded with the edge of the carpet disposed in the space beneath the upper section. the upper section having on its upper surface means for holding the carpet against backward movement with respect to the edge so that any tendency for the margin to move out of engagement with the edge will be restrained.

A feature of the invention resides in the uninterrupted free edge about which the margin is folded, for this edge, while it forms a secure anchor for the margin of the carpet, nevertheless, permits the edge of the carpet Vto be withdrawn from under said upper section. by the use of a suitable tool and raised from the fastening means in the event that adjustments in the carpet are required.

While the attaching strip may be made of various types of bendable metal, it is presently preferred to make it of a suiciently rigid material so that it will hold against bending inci.

form an upper sectionl I2 vand a lower section I3. It is presently preferred to make the bend I I in the form of a reverse bend so that the upper and lower sections project therefrom. This enables the lower section I3, which is to be secured to the iioor, to be readily accessible. This section may be secured in position in many ways. As herein illustrated, the section is provided with apertures I4 through which securing means such as nails or screws I5 are driven.

The bend, as shown in Fig. 2, is preferably of a height so that the upper surface of the upper section is flush with the upper surface of a pad I6 which may be placed under the carpet.

The upper section as shown in Fig. 1 has an uninterrupted smooth straight free edge I'I along the free edge thereof. When the fastening device of the present invention is installed, it is secured in-position, for example, adjacent the wall I8, as shown in Fig. 2, with the free edge II in spaced relation therewith. The carpet I9 is disposed over the fastening device and has its margin folded around the free edge with the edge of the carpet disposed in the space between the upper section and the floor. This forms a bite about the free edge which tends to hold the carpet in position.

In order to further hold the carpet against movement, the upper section is provided with a carpet-piercing means which engage and hold the carpet against movement back from the free edge which might cause the carpet edge to pull from under the upper section. While this piercing means may take many forms, it is herein illustrated as an integral tang 2U lanced from the upper section between the free edge and the bend and projecting upwardly above the upper surface of said section and facing toward the free edge. These tangs may be arranged as required. In the herein illustrated form of the invention the tangs 20` are arranged in two rows in staggered relation.

In operation, the fastening device is placed on the floor adjacent the wall or inwardly of the edge of the carpet and secured in position by securing means I5 passing through the apertures I4 in the lower or floor-engaging portion I3. The pad IB is put in position and the carpet I9 laid so that its margin overlies the fastening device. The margin is then folded back tightly about the straight edge II of the fastening device as shown in Fig. 2 and the edge of the carpet is disposed in the space between the floor and the upper section I2. In this position it will be seen that the carpet forms a bite about the free edge. As the carpet is drawn taut cthe piercing means will extend into the back of the carpet and will hold the carpet against any further movement to the rear.

When it is desired to unfasten the edge of the carpet to remove the carpet or to adjust its position, this may be readily done by withdrawing the edge of the carpet from under the upper section by means of an awl or other similar pointed instrument. Inasmuch as the free edge is continuous and straight and does not pierce the carpet, the carpet can be readily lifted free of engagement with the free edge and the carpet.

disengaged from the tangs for adjustment. or

sired length and of suiiicient rigidity. that it isrl not readily bent by the normal'forces applled to the carpet while in use.

The device of the present invention can be readily formed from a sheet or` strip of metal by. a stamping and piercing operation so that its` manufacture is inexpensive. Further, because. of the structure of the. fastening device it can be easily installed and will eiciently and securely hold the carpet in place andyet permit it to be readily released when desired for. removal or readjustment.

Variations and modifications may be made within the scope o f this invention and portions of the improvements may be used without others.
